DISCHARGE YOUR BODY’S STATIC ELECTRICITY BEFORE TOUCHING PCB AND/OR UNIT. AN ELECTROSTATIC DISCHARGE CAN ADVERSELY AFFECT ELECTRICAL COMPONENTS. USE THE FOLLOWING PRECAUTIONS DURING INSTALLATION AND SERVICING TO PROTECT THE PCB FROM DAMAGE: 1. DISCONNECT ALL POWER TO THE UNIT. DO NOT TOUCH THE PCB OR ANY WIRE CONNECTED TO THE CONTROL PRIOR TO DISCHARGING YOUR BODY’S ELECTROSTATIC CHARGE TO GROUND.2. FIRMLY TOUCH A CLEAN, UNPAINTED, METAL SURFACE OF THE UNIT AWAY FROM THE CONTROL.BY PUTTING THE UNIT, THE CONTROL, AND THE PERSON AT THE SAME ELECTROSTATIC POTENTIAL, THESE STEPS WILL HELP AVOID EXPOSING THE PCB TO ELECTROSTATIC DISCHARGE.

DO NOT CONNECT TO OR USE ANY DEVICE THAT IS NOT DESIGNED CERTIFIED BY THE MANUFACTURER FOR USE WITH THIS UNIT. SERIOUS PROPERTY DAMAGE, PERSONAL INJURY, REDUCED UNIT PERFORMANCE AND/OR HAZARDOUS CONDITIONS MAY RESULT FROM THE USE OF SUCH NON-APPROVED DEVICES.

WARNING

ONLY PERSONNEL THAT HAVE BEEN TRAINED TO INSTALL, ADJUST, SERVICE OR REPAIR (HEREINAFTER, “SERVICE”) THE EQUIPMENT SPECIFIED IN THIS MANUAL SHOULD SERVICE THE EQUIPMENT. THE MANUFACTURER WILL NOT BE RESPONSIBLE FOR ANY INJURY OR PROPERTY DAMAGE ARISING FROM IMPROPER SERVICE OR SERVICE PROCEDURES.

PROGRAMED INVERTER PCB KIT INSTRUCTIONS:WARNING: Discharge your body’s static electricity before touchingPCB and/or unit. An electrostatic discharge can adversely affectelectrical components. Use the following precautions duringinstallation and servicing to protect the PCB from damage. Byputting the unit, the control, and the person at the same electrostaticpotential, these steps will help avoid exposing the PCB toelectrostatic discharge.

HIGH VOLTAGE! DISCONNECT ALL POWER BEFORE SERVICING OR INSTALLING THIS UNIT. MULTIPLE POWER SOURCES MAY BE PRESENT. FAILURE TO DO SO MAY CAUSE PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.

WARNING

1. Disconnect all power to the unit. Do not touch the PCB or anywire connected to the PCB prior to discharging your body’selectrostatic charge to ground.

2. Firmly touch a clean, unpainted, metal surface of the unitaway from the control.

3. Note location of all wiring and plug terminals (recommendpictures) and remove all wiring from PCB.

NOTE: Thermal grease applied between the heat sink and therefrigerant loop allows for proper cooling of the PCB circuits(IGBT’s). Failure to apply the grease on the cooling loop may resultin an insufficient cooling circuit. Only use thermal greasepart # 9S00859.

4. Remove the screws from the cooling loop cover to allow it tohinge open. (Figure 1)
